seagate disk wizard os check, server 2008

Ive been trying to install seagate disk wizard, but it complains about installing on a server os, so i used orca to remove the os check, but now it goes past the os check and is asking for a serial\reg number!

This is free software to use with seagate\maxtor drives (i have both installed) anyone know if there is a free reg number i can use (like AVGfree, on install gives a free key) ? I think i deleted a switch or 2 too many
